96239818 CONNECT MRE DUC MWMR
2
The CONNECT MRE DUC MWMR microwave presence detector switches are designed to provide automatic control of lighting loads via the Connect marshalling box. The CONNECT MRE DUC
MWMR detects movement using a highly sensitive microwave detector and turn the load on. When an area is no longer occupied the load will switch off after an adjustable time out period. This microwave works by emitting low power microwave signals and measuring the reflections as the
signals bounce off moving objects. The detector also has an integral light sensor which can provide the following optional features:-
With Connect dimming marshalling boxes, the unit can provide a maintained illuminance (or
daylight linking) feature. The internal light sensor measures the light level in an area and will automatically adjust the output of the luminaries, via the marshalling box, to maintain a constant, adjustable lux level. Please note that this function only works with Connect dimming
marshalling boxes using either DALI, DSI or analogue (1-10V) dimming ballasts.
―Lux hold off‖ with non-dimming marshalling boxes, to prevent lighting coming on when a person
first enters the area if there is sufficient ambient light present (only available using the
SWITCHLITE IR PROGRAMMER programming handset - please see below).
―Lux switch off‖ with non-dimming marshalling boxes, to switch lighting off during occupancy if
the light level rises above a certain lux level in an area, which is sometimes required if ambient
light affects the area during certain times of the day (only available using the SWITCHLITE IR
PROGRAMMER programming handset - please see below).
When the unit is first powered up the microwave sensor will always detect immediately regardless of
whether the room is occupied or not. An integral IR sensor in the unit allows the additional functions to be used in conjunction with :-
Programming Handset (Part No. SWITCHLITE IR PROGRAMMER) the following additional functionality is available for commissioning purposes:-
Setting the time delay.
Sensitivity (range) adjustment.
Walk test LED - to check that the detector is picking up movement in the area.
Set the maintained illuminance lux setting on dimming marshalling boxes.
Set ―lux hold off‖ and ―lux switch off‖ levels on non-dimming marshalling boxes.
The SWITCHLITE IR PROGRAMMER programming handset should only be used by specifically
trained personnel for commissioning purposes only.
2. Description & Operation
3
1. Connect a Cat 5 (RJ45) patch lead from the back of the sensor to the relevant port on the Connect marshalling box. An additional RJ45 connector is provided to daisy chain sensors
together when being used with non-dimming marshalling boxes.
2. The detector should be sited so that the occupants of the room fall inside the detection pattern
shown in section 5.
3. The detector should be sited so that the occupants of the room fall inside the detection pattern
shown in section 5, at a recommended ceiling height of 2.8m (note: the higher the sensor is
installed the shorter the detection range will be).
4. Sites as far away as possible from any lighting or ventilation equipment.
5. Do not fix to a vibrating surface.
6. Do not fix to a suspended luminaire.
7. Site as far away as possible from the surface of metal objects.
8. Mount using one of the two options overleaf.
9. Power the unit up - the load should come on immediately.
10. Vacate the room or remain very still and wait for the load to switch off (this should take no
more than 2 minutes).
11. Check that the load switches on when movement is detected.
12. If required, adjust the sensitivity level down to reduce the range of detection.
13. Using the SWITCHLITE IR PROGRAMMER programming handset - please refer to Section 4
(page 7 to 10) for setting the parameters.

LIGHTS DO NOT COME ON
Check to see if the Connect marshalling box is powered up and the wiring is correct. Disconnect both RJ45 connections on the Cat 5 patch lead and re-connect, ensuring that they ―click‖ into position, making good connection.
Check that the ―lux hold off‖ setting is
not keeping the lights off because there is sufficient ambient light.
If the detection range is smaller than expected, check the diagram above. Rotating the sensor slightly may improve the range.
If the LED is flashing at regular
intervals, this shows that the detector is being overridden. Press the cancel button on the handset.
LIGHTS DO NOT GO OFF
Ensure that the area is left unoccupied for longer than the selected timer setting.
Make sure that the sensor is not adjacent to circulating air, heaters or lamps and not on a vibrating surface or in the view of moving objects.
If the LED is flashing at regular intervals, this shows that the detector is being overridden on. Press the cancel button on the handset.
